@bsky.app Why have you allowed a verified ICE account. What's wrong with you? Why give credence to a fascist, paramilitary organisation?

Very happy to see this last thesis paper in press @natcomms.nature.com! We combine intracranial EEG with multimodal MRI to study how interregional similarity in neurophysiology relates to different network scales ⚡ 🧠

Full story 👇
www.nature.com/articles/s41...

We collected ~4.7 hours of task data on 3 participants, listening to 10 different categories to create a functional gradient space in which we could situate category structure, and infer acoustic and semantic dimensions.

Oh also, the data is open access! 👉 openneuro.org/datasets/ds0...

Auditory Cortical Gradients Integrate Bottom-Up and Top-Down Structure During Natural Sound Categorisation Understanding how the brain organises natural categories is a central challenge in neuroscience. While prior work has shown that categories can be decoded from distributed activity patterns in auditor...

🧠🔊 New preprint!
How does the brain organise natural sound categories?

In our new fMRI study, we show that auditory cortex arranges sounds along continuous functional gradients, where acoustic and semantic structure are integrated into a shared representational space.

I worked with Jonny for 5 years during my formative years as a scientist. He influenced how I see life deeply. Although I won't hear him explain things to me again, his words and kindness will live through those whom he inspired. We were so lucky to have him in our lives. We miss you a lot, Jonny.

I was so lucky to have Jonny as my PhD supervisor. He was a one-of-a-kind scientist and person. He continues to be an inspiration to me and I will always be guided by the way he thought about science and life. He built an amazing network of wonderful people and we all miss you, Jonny.

Obituary – Jonathan Smallwood

Jonny Smallwood @themindwanders.bsky.social was a beloved friend and mentor. He was taken from us too soon. His was a beautiful mind who understood the beauty of minds. As ever before, his kind voice guides me and his work will continue. We miss you Jonny. www.cbs.mpg.de/news/obituar...

Precon_all is finally citeable! I’m relieved, pleased, thrilled and all other superlatives to present to you our preprint describing the inner workings of the precon_all pipeline for semi-automated non-human cortical surface reconstruction! www.biorxiv.org/content/10.1... 1/10

I'm planning to write an editorial in @brain1878.bsky.social entitled "If patients only knew".
It's about obstacles that slow down or prevent people from participating in clinical studies and the pace of initiating #ClinicalTrials. If you have experience or comments please message me and repost.

Just to be clear this is not something we can tell from this study and any suggestion that it might be seems dangerous to me.

This accumulating process has been obvious since at least 2021. I assumed Labour would reluctantly intervene to help. That they won't almost guarantees that UK academia will become an even more cruel/anti-intellectual place to work, even for those in RG universities. So I'm leaving.

What an absolute pleasure it was to welcome the brilliant @f-geranmayeh.bsky.social for our seminar series at @psychologyuea.bsky.social. Fascinating and important work on using LLMs in stroke. Great speaker :)

If anyone is interested in coming to London to work on interesting computational psychiatry questions feel free to get in touch!

The end of the mass university era in England and Wales is now base case in my view after the last week. Much of Blue Labour, much of Britain's Right and a great number of voters will welcome that. But it's an interesting and arresting example of minoritarian state policy capture.

"UPFs affect health beyond the individual impact of high content of critical nutrients – sodium, trans fats and sugar"

< This study does not show this.

Food that's high in salt, trans fats, and sugar are bad for health.

Whether the 'ultra processing' makes any difference to this is unknown.

two points on EHRC advice on trans people's use of public toilets:

1) trans people are being required to out themselves when using loo in public

2) how is it enforceable? What about cis people who don't conform to stereotypical appearance?

it's shit.

[1/5] I'm very happy to share that our latest paper: “SIM: Surface-based fMRI Analysis for Inter-Subject Multimodal Decoding from Movie-Watching Experiments”, has been accepted to #ICLR2025! 🎉

Come see our poster #61 at 3pm @iclr-conf.bsky.social #iclr2025 surface deep learning for generalising fMRI decoding across different human brains with @dahansimon.bsky.social @gabriben.bsky.social

Fuck the EHRC. Inhumane Trumpian bullshit

From our 'infant sibs' cohorts we are finding increasing evidence for Chronogeneity as a way to view heterogeneity in autism. In other words, different ages of onset may reflect different types of neurodiversity.

Distinct synaptic plasticity rules operate across dendritic compartments in vivo during learning Synaptic plasticity underlies learning by modifying specific synaptic inputs to reshape neural activity and behavior. However, the rules governing which synapses will undergo different forms of plasti...

Our new paper is out in Science.

What is the synaptic plasticity rule in the brain, we asked. It turns out there are multiple, even within individual neurons.

Congrats Jake!

Incredibly flexible simulator brought to you by the talented @michielcottaar.bsky.social. Can feed arbitrary sequences (e.g. with pulseq) and model lots of microstructure features (diffusion, permeability, susceptibility, MT). Allows multimodal simulations. Fully documented and open. :)
